Vthe coin artment. When the guard plates between the lower guard-plate and bottom 'of the compartment, a removable securing 'grasping the spring members or catches 3 6 -be renewed.

' what I c aim as new lt will be readilyseen that when it is desired to remove the upper guard-plate, either for the purpose of renewing said plate or removing:r the journal-box from the axle, it is only necessary to lirst remove the securing device. 'and 'this is accomplished by simply ein towards each other until they disengagc the stop-shoulders 38, when the said device is free to he withdrawn. After the securing device is withdrawn the guard-plate may he removed vertically from and pressing t are in p acethey cover the openings' 25, and being held in close contact with the axle will I efl'ectually prevent the ingress of any dirt, grit or other substance, thus protecting the iearing surfaces from foreign matter.

From thev foregoing description, in connection with thev accompanying drawings, the construction, operation and practical advantages of my' invention will be readily understood, and it will he noted that the lubrication and rotection of the bearing surfaces ofthe ax e and bearing-block is very, efl'ective'; and that the parts 'which are subject to wear, to wit, the guard-plates 26 and 27 are readily removable so that they may Havin thus described my invention, and desire to secure by Letters-Patent, is:-

1. In a car-axle journal box, the combination with a box having a vertical compartmentl open at, its up er end and through which compartment t e axle is adapted to ass transversely, and provided with stopshoulders at the upper ends of the compartment, of guard-plates slidably and removably mounted in the compartment and having overlapping flanges, springs interposed between the lower guard plate and bottom of'the compartment, a removable securing device located in the upper end of the compartment and havin spring members engaging the stop-shou ders, and-a spring interposed between the securing device and upper guard-plate. 2; In a car-axle journal box, the combination with a box having a vertical compartment open at its upper end and through which compartment t ie axle is `ada ted to pass transversely, and provided wit stopshoulders at the upper ends of the coinpart ment, of guard-plates slidably and removably mounted in the compartment and having overlapping flanges, springsv interposed device located in the upper end ol' the coinpartment and having spring members cngnging the stop-shoulders, and a boss formed on its inner side, a wear-plate bearingu ion the guard-plate and having a boss on a ine with the .aloresad boss, and a helical spring e ses and suhinterposed between the securing device v f tir-:flute and engaging the bosses, stantially as shown and described'.

3. in a car-axle journal box, the combination with a box having a vertical compartment .o en at its upper end and through which t-lie axle' passes transversely, and provided with stop-shoulders at the upper end of the compartment, of guard-plates sliflable in the compartment and havinff overlapping flanges, springs interposed zbetween the lower guard plate and the bottom of the compartment, a removable securingdevice located in the upper end of the compartment and Vcomprising a horizontal portion having downwardly and upwardly projecting spring members, the upwardly projecting members having shoulders which engage the stop-shoulders of the box and ternunate in hand-grasping portions, and a spring interposed between the horizontal portion ofthe securing device and the u per guard-plate, substantially as shown an described. i

4. In a car-axle journal box. the combination with the axle and box, the latter having a vertical compartment open at its upper end and through, which compartment the axle passes transversely, and provided with stop-shoulders at the upper end of the compartment, of guard-plates slidable in the compartmentto embrace the axle and having overlapping llanges, springs interposed between the lower guard-plate and bottom of the compartment, a removable securing device located in the upper end of the compartaient and comprising a horizontalportion having downwardly and upwardly projecting spring members at its ends, the upwardly-projecting members having shoulders which engage the stop-shoulders of the boa and the horizontal portion of the securing device having a boss' on its underside, a wear-plate bearing on the upper guardplate and havin a boss on its upper side, and a helical spring interposed between the securing device and wear-plate and engaging at its ends with the aforesaid bosses.

5. In a car-axle journal-box,the combination, with a box having a vertica'l compartment at its rear end through which the axlel passes transversely, the opposite end walls of said compartment having stopshoulders at their upper ends, of guard-plates slidably mounted in the vertical compartment and adapted to bear against the upper and lower sides of the axle and having overlapping flanges, springs interposed between the bottoni ol' t e compartment and lower guard plate, and a securing device for the upper guard plate comprising a horizontal portion with downwardly projecting members at its projecting spring iiicnihers or catches having shoulders which engage the stop shoulders at the upper ends of the compartment, and
